Many model options serve all the traditional amplifier applications in an extended optical link: booster, in-line, andpre-amplifierA booster amplifier operates at the transmission side of the link. It features high input power, high output power, andmedium optical Gain .
Boosters are designed to amplify aggregated optical input power for reach extension.An in-line amplifier operates in the middle of an optical link. It features medium to low input power, high output power,high optical Gain , and a low noise figure. In-line amplifiers are designed for optical amplification between two networknodes on the main optical link.
A pre-amplifier operates at the receiving end of an optical link. It features medium to low input power, medium outputpower, and medium Gain .
Pre-amplifiers are designed for optical amplification to compensate for losses in ademultiplexer located near the optical receiver.Some EDFA models include an additional mid-stage port designed for insertion of a Dispersion CompensationManagement (DCM) unit without its inherent insertion loss. The design of these models maximizes the DCM benefitsto increase deployment flexibility.
New placement options require fewer amplifiers in the link, and they can open thedoor to applications that were not possible with older technology.Some EDFA models include an Red and blue port designed for Single fiber DWDM Solution. The design of thesemodels is used for single-fiber DWDM transmission systems.
